IDFDataCanada.jl

IDFDataCanada.jl offers methods to get ECCC IDF data in CSV (.csv) or NetCDF (.nc) format from the .txt files via automatic download and extraction from .zip archives on ECCC's server.

Ouput Format

CSV

By choosing CSV format, it will return a .csv file for each station of the selected province with ECCC Short Duration Rainfall Intensity-Duration-Frequency Data from Table 1: Annual Maximum (mm).

Stations information is returned in a CSV file named info_stations.csv :

NetCDF

By choosing NetCDF format, it will return a .nc file for each station of the selected province with station informations and ECCC Short Duration Rainfall Intensity-Duration-Frequency Data from Table 1: Annual Maximum (mm).
